Living in Western New York (Buffalo - Niagara Area), can I grow a Passion Flower vine tree year round outdoors? I know it is an annual but will it survive cold winters? Will I have to cut it down, dig it up and bring it indoors for winter or will a heavy mulch cover protect it from the winter cold/snow?
If you live very near the falls so that you are in zone 6, you may be able to get a standard purple passion flower to survive in the ground year round if you plant is somewhere sheltered and it is mulched well in the winter. This is the lowermost zone that it can survive in and the purple passion flower is considered to be the hardiest.
My passion flower (maypop) is a container plant on my porch. This is the first time I have ever had one. . . and it is the most amazing flower ever. I have two issues of concern. First, the flowers bloom and then the next day they are gone. . . not even a shred of evidence they were ever there the next day. Could something be coming along at night and taking them? How long do the flowers usually last once they have bloomed? Second, I noticed that some of the immature blooms never get there and just fall to the ground. Could I be giving too much water? I have it on the porch and it gets sun and shade but not harsh direct sun. Would it prefer the hard afternoon sun?
Several things could be affecting the plant. You may have given the plant too much nitrogen. This causes vigorous growth but little in the way of blooms. You can counter this with adding more phosphorous to the plant. Bone meal is an excellent source of bone meal.
There is a good chance that your bud drop is due to a moisture problem. Passion flower requires plenty of water during the growing season. Low humidity can also cause the buds to dry up and drop.
Your plant could also have some type of pest problem. Tretaing it with neem oil should help with this.

We have a Passion Fruit vine (Banana Passion Fruit, Passiflora spp) which we want to try and move. Is this advisable? What would be the best way to go about it? Cut it right down (how much?)? It is not very big and only has 2 or 3 main stems that are about a meter and a half or so long. We have had it less than a year. Is it the right time of year (winter here in Sydney, Australia)? Any other tips or reasons why we should not do it?
